Signal flow/gain staging diagram for Octatrack MKII

Is there a signal flow or block diagram for the Octatrack MKII? I found lots of text but no diagrams, so here’s my attempt trying to visualise the level & volume controls if it’s any use. The lines show possible connections; they’re not all active at the same time. Am new to the machine so just feeling my way here
